2. Occurs on the surface
3. Occurs at any temperature
4. Slow

Question 6

What happens when a substance is heated

Answer 6

It gains energy and the particles moves about much more quickly. The distance between the particles also increase. Causing the volume to increase

Question 7

What happens when a substance is cooled

Answer 7

It looses energy and the particles moves about much more slower. The distance between the particles also decrease. Causing the volume to decrease.

Question 8

What is diffusion in particles

Answer 8

The movement of particles in a region of a higher concentration to a lower concentration
